text: The behavior of antibubbles differs from that of air bubbles in three primary ways, and provides a ready means of identification:
  * Antibubbles are held in place by surface tension, and move rapidly across the surface of the water. They can also be seen to ricochet off other objects in the water (such as air bubbles) and off the sides of a container in a manner similar to that of billiard balls.
  * Under ordinary circumstances, antibubbles are short-lived. An air bubble with a soap skin may last several minutes. Antibubbles often have lifetimes of a few seconds or less; however, if the electrical potential between the inner and outer fluid is equalized, antibubbles can last as long as, or longer than, air bubbles. Antibubbles with a lifetime of at least tens of hours can be produced by adsorbing colloidal particles at the air-water interfaces of the antibubble.
  * Antibubbles refract light in a different manner than air bubbles. Because they are water droplets, light entering them is refracted back toward its source in the same manner as rainbows are produced. Because of this refraction, antibubbles have a bright appearance.
